Title: Photometry converter
Inventor: MAEDA YOSHIO
IPC: G01J1/44
Filed: 1977-11-09
Abstract: PURPOSE:To obtain an absolute digital value, which is highly linerarly proportional to the quantity of incident light, by interrupting the incident light upon a photoelectric converter in a preset period, by guiding the interrupted light into the photoelectric converting element, by amplifying the electric signals and by eliminating the DC component which is generated by the converting means. CONSTITUTION:Optical converting means 1, which is composed of a supply power source for a photoelectric converting element 11 such as a photoconductive element, detects incident light 10, which is interrupted by a chopper 71, so that the quantity  of the light may be converted into electric signals of voltage, which are fed to an amplifier 2. This amplifier 2 eliminates the DC component of the input signals and selectively amplifies only the AC component, which is then fed to an adder 3. This adder 3 adds a preset DC voltage to the AC component to generate a positive monopolar voltage, which is fed to an A/D converter 4. This converter 4 converts the input voltage into digital quantities, which are then fed to a memory device 5. On the other hand, the chopper 71 is turned by a drive motor 72 to interrupt the incident light in a preset period. Thus, it is possible to stably operate the A/D converter.

IPC: C02F1/68
Filed: 1978-11-01
Abstract: PURPOSE: To prevent the crystallization of calcium carbonate as well as to raise the utilization rate of carbon dioxide in making drinking water by the method in which slaked lime is added to distilled water and then the distilled water is brought into contact with carbon dioxide to dissolve calcium carbonate and calcium bicarbonate in the distilled water.  
     CONSTITUTION: Distilled water containing slaked lime is introduced through the line 7 into the lower part of the bubbling tower 8 and also carbon dioxide gas is supplied through the porous material tube 10 from the line 9 into the lower part of the bubbling tower 8 while being dispersed in fine bubbles, where the slaked lime- containing distilled water and the carbon dioxide gas are flowed in parallel in the bubbling tower 8 so as to make a vapor-liquid contact, whereby slaked lime and carbon dioxide are reacted to form calcium carbonate and calcium bicarbonate.  The water containing the calcium carbonate and calcium bicarbonate is drawn out  of the upper part of the bubbling tower 8 through the line 12 to obtain a drinking water.

Title: Cathode structure
Inventor: NIIRU AREKUSANDAA KEIDO
IPC: H01J1/304
Filed: 1993-05-12
Abstract: PURPOSE: To increase a field emission current and improve its stability by depositing a coating material on a cathode chip evaporating or sputtering the coating material. CONSTITUTION: A field emitter cathode structural body is supported by a substrate with a cathode chip 1 tapered on the substrate and an insulating spacer layer 7, and is formed with a grid layer which has an aperture substantially located in a coaxial position with the cathode chip 1. And, a thin coating 11 is formed by depositing a coating material on the entire cathode structural body evaporating the coating material from an evaporation source 8. Here, since the aperture 9 in the insulating spacer layer 7 has a larger diameter than the aperture in the grid, etc., the coating material is not deposited on surrounding walls of the aperture 9 in the insulating spacer layer 7. Therefore, when the field emission cathode structural body is used, a short-circuit is not caused between the cathode chip 1 and the grid layer.

Title: Mixed medicinal liquid treating apparatus for treating chemical liquid containing sulfuric acid and peroxide
Inventor: INAGAKI YASUSHI
IPC: H01L21/306
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a treating apparatus capable of treating a spent sulfuric acid liquid contg. peroxide to a recyclable state. SOLUTION: This chemical liquid treating apparatus has a medicinal liquid treating vessel 1 which treats the material to be treated by the mixed chemical liquid contg. the sulfuric acid and the peroxide as essential components and a decomposing vessel 3 which is supplied with a decomposition accelerator and forcibly decomposes the peroxide included in the used waste liquid after the treatment. The chemical liquid treating vessel 1 and the decomposing vessel 3 may be separately disposed or the medicinal liquid treating vessel 1 may be utilized as the decomposing vessel. In the case of the former, the apparatus is provided with a transfer means for transferring the waste liquid of the mixed chemical liquid from the chemical liquid treating vessel 1 to the decomposing vessel without dilution. The utilization of a storage tank 4 as the decomposing vessel is possible as well.  Rapid foaming does not occur any more and oxidation power degrades if the peroxide is forcibly decomposed in the decomposing vessel 3 by adding the decomposition accelerator to the waste sulfuric acid liquid contg. the peroxide. The waste sulfuric acid liquid of such a state is easy to transport and convey and may be recycled if the liquid is purified.

Title: Instant film unit
Inventor: SUEKAWA SHINYA
IPC: G03C8/46
Filed: 1987-05-29
Abstract: PURPOSE:To prevent infiltration of a developing soln. into a metallic foil layer even during long-period preservation by laminating a thermoplastic lining layers having alkali resistance in two plies on the side of a pod for sealing the developing soln. where the soln. is enveloped in the metallic foil. CONSTITUTION:The pod 4 mounted on the surface of a drawing out sheet 2 is constituted of 4 layers; a paper layer 40, an aluminum layer 41, a PVC layer 42, and a PVC layer 43. Formation of the PVC layers 42, 43 on the aluminum layer 41 is executed by coating an adhesive agent for lamination on the layer 41, superposing a PVC sheet thereon in a half-dry state and drawing the sheet out of a spacing between press rollers under heating. The PVC 42 is, therefore, laminated on the layer 4. The PVC layer 43 is laminated on the layer 42 by repeating the same procedure. The number of pinholes is thereby decreased to the number much smaller than in the case of using one thermoplastic lining layer and the infiltration of the developing soln. to the metallic foil is prevented even during the long-period preservation.

Title: Immobilized enzyme and its preparation
Inventor: KIHARA YASUO
IPC: C12N11/12
Filed: 1982-07-30
Abstract: PURPOSE:To prevent the deactivation of enzyme in immobilization, by applying the enzyme layer and the second polymeric gel layer to the first polymeric gel layer formed on the surface of a porous membrane, and crosslinking at least the first gel layer. CONSTITUTION:The surface of a porous membrane is coated with the first gel layer composed of a water-soluble polymer. The gel layer can be formed by passing the membrane forcibly to an aqueous solution of the waterl-soluble polymer. By using a gel layer composed of a water-soluble polymer, the hydrophilic property of the membrane can be improved and the permeation of the reaction water solution through the membrane can be faciliatated. The first gel layer is crosslinked to prevent the dissolution in the aqueous system in which the enzymatic reaction is performed, and to enable the stable support of the gel layer carrying the enzyme. Since the crosslinked gel layer has a fractional molecular weight of usually <=10,000, the second gel layer containing the enzyme can be applied effectively on the first gel layer by passing the aqueous solution containing the enzyme and the second water-soluble polymer forcibly through the first gel layer, thereby capturing the enzyme with the first gel layer.

IPC: H02P9/30
Filed: 1986-06-12
Abstract: PURPOSE:To enable the stable AC power to be supplied smoothly, by detecting inrush current and short-circuit current, and by controlling the secondary voltage of an exciting transformer. CONSTITUTION:In starting a motor 12 if a large amount of inrush current flows, an inrush current and short-circuit current detecting device 38 detectes this inrush current and gets a contact 42 to actuate which is set on the secondary winding side of an excitation transformer 40.
